f; 11 ma {I TTORNEy United States Patent "ce 3,929,516 QUICK DETACHABLETELESCOPE GUN SIGHT William J. Clee, 3745 Brownsville Road, Trevose, Pa.Filed June 30, 1960, Ser. No. 39,930 1 Claim. (CI. 33-50) This inventionrelates to telescope gun sight mounts of the type having a mounting barprovided with means for attaching it at its ends to a gun frame in sucha manner as to permit vertical and lateral angular adjustment of the barin relation to the bore of the gun barrel for elevation and windagecorrections, the bar having upwardly projecting arms for detachablyclamping a telescope in a fixed position above the gun barrel.

The principal object of the present invention is to provide a telescopegun sight mounting of the general type referred to having means toenable the quick detachment of the telescope sight from one gun andattachment to either of a number of others, as, for example, from alarge caliber rifle to one of smaller caliber, or vice versa. With thisimprovement ahunter can carry two or more rifles of difierent calibershaving attached thereto correctly adjusted mounting bars provided withuniform seats for a pair of clamping rings or collars attached to asingle telescope sight, and quickly mount the sight on either of theguns When required, without the need for any readjustment of themounting bar on the particular gun.

Itis of the utmost importance in the use of a single telescope sight forseveral guns that the sight be capable of transfer from one gun toanother in the quickest possible time, as, for example, in the event ofthe appearance of large game when the sight is attached to a rifie ofsmall caliber.

In previous telescope gun sight mounts of the type referred to, of whichI am aware, considerable time is required in effecting the transfer ofthe sight from one gun to another because of the number of manipulationsre: quired in the operation, not only rendering the telescope sightdifficult to attach to the mounting bar but necessitating that the barbe angularly adjusted for elevation and windage after attachment of thesight to the gun.

In my improved telescope gun sight mount the upwardly projecting armsfor supporting the telescope sight are provided with laterally openpairs of seats having plane surfaces for interfitting engagement withcorre sponding similarly formed projecting surfaces of theadjacentclamping members for holding the telescope sight normally inalignment with and above the'gun bore. Thus, assuming that the bar hasbeen correctly adjusted for elevation and windage, and that thetelescope sight; has been clamped with the sighting hairs in correctposition, it is necessary only to place the clamping members in theseats in the arms and thread a single screw in the rear of each of thearms into a registering opening in the adjacent clamp, or to apply a nutto a single stud. The telescope sight will then be in correct positionand condition for the gun on which it has been installed. Cony; wh n iis re vii'edlo transfer the sight other gunit is necessary only to backthe rear screws out of the clamps and secure them with the correspondingrswsii hast r stfi a arms of the mounting bar in the other gun ent retransfer can be made in a few seconds.

3,029,516 Patented Apr. 17, 1962 are applicable'not only to topmountings but also to side mountings provided with means for angularadjustment of the bar for elevation and windage. The pairs ofinterfitting seating surfaces may however be arranged in verticallyspaced, and horizontally parallel relation, with the seats in thesupports open toward the telescope sight.

Other objects and advantages of my invention will appear or be pointedout in the following specification taken K in connection with theaccompanying drawings,- in

which FIG. 1 is a side elevation of a rifle having a telescope sightmounted thereon in accordance with my invention;

FIG. 2 is a section taken on the line 22 of FIG. 1; FIG. 3 is a sectionsimilar to FIG. 2, but with the telescope sight removed; a

FIG. 4 is a fragmentary side elevation similar to FIG.-

FIG. 9 is an enlarged section of the telescope sight and mounting clamp,as shown in FIG. 2;

FIG. 10 is a fragmentary top plan view of the rifle shown in theprevious views with the mounting bar re moved, and with one of thevertical adjustment nuts in correct position;

The interfitting'seating surfaces of the supports and FIG. 11 is atransverse section through a modified form of telescope supporting armand adjacent clamping member; and I FIG. 12 is a detail sectional viewof a further modified form of my invention. a

Referring to the drawings in which like numerals des-' igna-te likeparts in the several views, 10 indicates the intermediate portion of aconventional modern rifle to the frame portions 12 of which is attacheda telescope sight mounting bar 14 above and in normal alignment with theherein the barrel 13 and on which is mounted a conventional telescopesight 16. The mounting" baralso is similar to conventional designs,except that it is provided with distinctive improved clamping means forthetelescope sight. I v 1' In order to provide for angular adjustment,the mounting bar 14 is not attached directly to the frame portions 12 ofthe gun 10, but is pivotally and removably attached at one end 18 bymeans of transversely extending screws 20 to a block 22 which is rigidlysecured to the gun frame 12 by means of screws 24, or other suitablemeans. As illustrated, this block is on the forward portion of the frame12, but may be placed on the rearward portion and thus reverse theposition of the mounting bar, if desired. The inner faces 'of theheadsof the screws 2Q are recessed to form inclined surfaces 26 (FIG. 6)dc signed for coengagement at their bottom edges with complernentaryinclinedsurfaces 28 undercutin the top of the block 22 on opposite sidesof the block, and there: by rigidly but removably securing the mountingbar 14 r o e frame .13 5 fl n FIG. i e m u ting ba 14 is in normal axialalignment with the gun barrel, but it may be laterally adjusted ineither direction by backing out one of the screws 20, which are inthreaded engagement with the mounting bar 14, and driving the oppositescrew inwardly. The mounting bar is recessed on each side, as indicatedat 30 to permit limited inward movement of the heads of the screws 20,in ad justing the telescope sight for windage correction. When thescrews are tightened against the block 20 a narrow space 32 is leftbetween the mounting bar and the block 22, to permit a slight verticallypivotal movement of the bar in adjusting the telescope sight fortrajectory elevation.

The opposite end of the mounting bar 14 is of lesser thickness than theend attached to the block 22 and is vertically counterbored on each sideto a substantially equal depth, as indicated at 34 (FIGS. 1, 4 andthereby forming a flat relatively thin end portion 36 having therein acircular opening 38 (FIG. 5) to fit loosely over a vertical stud 40anchored in the gun frame 12. Circular nuts 42 and 44 are mounted on thestud on each side of the end portion for clamping it to the gun frame invertically adjustable relation thereto. These nuts are partiallyinclosed in the counterbores 34 which hold them and the mounting baragainst lateral movement. The mounting bar 14 is vertically adjusted tocorrect elevation of the telescope sight 16 by threading the nuts 42 and44 in the direction desired and thus moving the mounting bar 14 on itspivotal connection with the screws 20 at the opposite end of the bar.The nuts 42 and 44 may be provided with peripheral sockets 46 to beengaged by a slender tool (not shown) or with other suitable means tofacilitate manual rotation of the nuts.

For supporting the telescope sight a pair of upstanding and laterallyoifset arms 48 are formed integrally with or otherwise rigidly carriedby the mounting bar 14 in longitudinally spaced relation between theblock 22 and the vertical stud 40. These arms have uniform pairs ofplane clamp seats 50 in V or similar formation one above the other anddiverging toward the center line of the ends of the mounting bar, theseseats being open to receive correspondingly shaped projecting planesurfaces 52 on a pair of telescope clamping members 54, insertedlaterally, in precise interfitting relation. Single headed screws 56 areinserted horizontally in the arms 48 midway between the seats 50, andafter seating of the clamping members 54 these screws are inserted inaligned threaded openings 58 in the clamping members 54. The clampingmembers 54 and their complementa'ry members 60 have semicircularopenings 62 corresponding to the diameter of the portion of thetelescope sight 16 to be engaged, the two members being rigidly clampedabout the telescope sight, after rotary adjustment to bring the crosshairs into correct relation, by means of screws 64, the two clampingmembers forming a 'unitary collar rigidly but detachably mounted on thetelephone sight 16.

An essential feature of my improved gun sight mount resides in thearrangement whereby the clamping members 54 remain rigidly attached tothe telescope sight and in which the mounting bars 14 on the variousguns to which the sight is to be detachably mounted have previously beencorrectly adjusted for elevation and Windage, so that when the V-shapedportions of the clamping members have been inserted in the complementaryV-shaped seats in the supporting arms 48, the telescope sight will beautomatically placed in correct position, without the need of anyfurther adjustment, irrespective Of whether the V-shaped seats in thearms 48 are open in a lateral or a vertical direction.

The plane seating surfaces 50 on the supports 48 may be in any laterallydivergent relation which will permit precise interfitting engagementwith correspondingly shaped telescope clamping members insertedlaterally of the mounting bar. Also, as shown in FIG.11, the arms 48 maybe provided with V-shaped grooves 66 and the clamping members 54 withV-shaped edges 68 to guide the clamping members to their centralposition in the arms 48, as well as to more positive locking engagementbetween the clamps and arms.

From the foregoing description it will be seen that with any number ofguns having correctly adjusted mounting bars 16 attached as shown inFIGS. 3 and 8 and with the telescope sight correctly clamped in members54 and 69, a quick transfer of the sight from one gun to either of theothers can be very quickly eifected by withdrawing the single headedscrews 56 in the arms 48, seating the telescope sight on the other gunand inserting the single screws 56 of the mounting bar 14 of that gun inthe openings 58 in the clamping members 54, these manipulationsrequiring only a few seconds.

The interfitting plane seating surfaces in the supports 48 and on theclamping members 54- may be laterally parallel, as indicated at 50a and52a, respectively in FIG. 12. -Also single studs 70 and wing nuts 72 forengagement therewith may be substituted for the threaded openings 58 inthe clamping members 54 and the screws 56 in the supports 48. The nutsmay be anchored to the supports against loss by wires or cords 74, orother suitable means. Portions 76 or all the interfitting seatingsurfaces of the supports and clamping members may be of V-forrnation 78,as indicated at 66 and 68 of FIG. 11 to guide the clamping members intocentral-relation in the seats of the supports.

In addition to the advantages mentioned, my entire improved telescopesight mount is simple and economical in construction; also my improvedmeans of adjustments of the mounting bars renders such adjustmentsquicker and more secure than is provided in similar previous devices ofwhich I am aware.

Obviously, various changes and modifications may be made in my improvedtelescope sight mount without departing from the spirit and scope of myinvention. Therefore, it should be understood that the embodiment of myinvention shown and described is intended to be illustrative only, andrestricted only by the appended claim.

I claim:

In a telescope gun sight mount, the combination of a telescope mountingbar having means for attaching it to a gun frame in fixed longitudinalrelation with the gun barrel and provided with a pair of integraltelescope supports having therein pairs of longitudinally aligned,outwardly diverging seats in substantially right angular relation; and atelescope gun sight having a pair of collars rigidly attached thereto,said collars having laterally projecting seating portions formed inoutwardly converging relation for interfitting engagement with thediverging seats in said supports; and headed screws for threadedinsertion in said supports and collars for drawing the outwardlyconverging portions of said collars into rigid interfitting engagementwith the diverging seats in said supports.
